1988–1995: Census Tracts 5,092.01 and 5,091.04 (1990 US Census); 1996–2005 Census Tracts: 5,092.01, 5,091.08 and 5,091.09 (2000 US Census); 2006–2011 Census Tracts: 5,092.01, 5,091.08 and 5,091.09 (2010 US Census)
Data for 2011 diagnoses are approximately 98 % complete, with about 3 % of cases not yet geocoded to a residential census tract
Expected rates were obtained from the Santa Clara region (Monterey, San Benito, Santa Clara and Santa Cruz counties)
SIR = standardized incidence ratio = observed number of cases/expected number of cases. The exact value of the number of expected cases is used in computing the SIR
If the 99 % confidence interval (CI) for the SIR contains 1, then any difference between the observed and expected number is not statistically significant
Kidney cancer includes cancers of the kidney and renal pelvis; liver cancer includes cancers of the liver, gallbladder, intrahepatic, and extrahepatic bile ducts
